CLOSURE FOR ooN'rAINERs;

Specification of Letters Patent. Patented Den. 142, 11915,

Application filed April 8, 1914. Serial No. 830,395.

To all whom it may concern:

Be it known that'I, MORTIMER BYE, a citizen of the United States,residing at Indianapolis, Marion county, and State of Indiana, haveinvented and discovered certain new and useful Improvements in Closuresfor Containers, of which the following is a specification.

My invention relates to closures for containers, and more particularlyto closure means adapted to hermetically seal a receptacle which isadapted to retain and aseptically protect a liquid, or other medicament,and in which it is desirable that the container should be quickly andeasily unsealed to permit of the ready utilization of the contents ofthe container, as for instance, for an injection, hypodermic orotherwise. I

The objects of the invention are to provide closure means which shall beeffective in antiseptically sealing the container, and yet may beinstantly and readily removed when p the contents of the container areto be utilized, and to also provide means of such a character that noportion thereof will become mingled with the contents of the containerwhen the seal is broken.

With these objects in view, my'invention is embodied in preferable formin the device hereinafter described and illustrated inthe accompanyingdrawings.

In these drawings, Figure 1 is a side view in elevation of a containerand closure embodying my invention; Fig. 2, a longitudinal section; andFig. 3, a view showing the container in section and the closure removedand separated from the container. j

The invention is shown .in the drawings as applied to an ampul, but itis capable of utilization with containers of various types and adaptedfor a variety of purposes, although it is to be understood that it isspecifically applicable to such containers as serve to hold a singlechargeof contents and in which the closure is merely operable to closethe container until the first and only use of the contents and is notthereafter replaced or retained.

Broadly stated, the invention consists of a closure for a singlechargecontainer which.

forms the sole closing means for the container, which is aseptic andwhich lies able adhesive and joint sealing medium, whereby upon a slightpressure or blow imparted to the closure member it may be easilydetached from the container, carrying with it the sealing substance in aclean separation, without leaving particles of the closure or sealingmedium in the dispensing channel of the container.

In the accompanying drawings, 1 is the body of a double end ampul, madeof glass,- as is usual, and adapted to contain a charge of a suitablemedicament in liquid form for injection or other mode of administration.The ampul shown has two contracted necks 2 and 3 providing restricteddispensing passageways, open at their ends. The invention, however, maybe applied to an ampul or other container having but one open end. Thecontainer is preferably provided at each open end with an outwardlyflared annular lip 4, which provides a seat exterior of and beyond thecontracted neck of the ampul, in which seat freely fits a loose,exterior closure member 5. This closure preferably consists of aspherical or otherwise curved body of antiseptic material, glass beingpreferably used, and it is placed loosely in the seat,

thus closing the end of the container. The closure 5 is securedremovably in place and the joint between the same and the containerhermetically sealed by means of a coating of adhesive material 6, suchas paraffin, or a composition of'a suitable nature. This sealing andsecuring medium is of such character that it may be readily broken orsevered by the application of a slight pressure to the closure. Aportion of the body of the closure member projects beyond the edges ofthe flared cup lessening the area of adhesive surface within the cup andenabling the member to more freely clearthe lip and to be readilyremoved. To enable the .closure to be more easily and promptly dislodgedfrom its seat, it is provided with a tongue 7, or similar projection,which also extends beyond the edge of the container and affords meanswhereby upon a slight pressure or blow imparted thereto, the closure andthe sealing medium adhered thereto may be detached from the container.

The flared seating end of the container provides a cup for the paraffin,or other adhesi-ve sealing medium, which provides a secure attachingsurface therefor and at the same time spaces thegreater part of theAlthough, of course, the loose exterior temporary closure member mightbe in the form of a disk of any suitable material and used with acontainer having a plain cylindrical mouth, yet the glass spherical bodyin conjunction withthe flared mouth of the container has been found toprovide aclosely fitting antiseptic and readily removable closure.

The invention is especially applicable for use in connection with ampulssince iten- I ables a wholly antiseptic container to be employed, andavoids the danger arising from the use of ampuls having closed' endsintegral with the glass body of the ampul, and

which must be broken to permit the use of r the contents, and in theutilization of which there is a possibility of particles of the brokenglass becoming mingled with the con-tents.

. .Having thus described my invention, what I claim is:

1. An ampul having a closure member seated loosely at the mouth thereofexterior of the neckof the ampul and projecting beyond thelip of themouth to facilitate removal and capable of ready dislodgment 'from saidseat by asli ht pressure, and a readily breakable adheslve sealihgmedium joining said member and container and confined to the surfacesthereof exterior of the neck, said member forming the sole closing meansfor said mouth.

2. Anlampul having a neck and an outwardly flaring mouth beyond saidneck, a

closure member larger than the neck area and loosely seated in saidmouth, a readily breakable adhesive sealing medium joining said memberand mouth and confined to the area beyond the neck opening, said memberextending beyond the lip of the mouth and 4 being readily dislodgeableby a slight pressure only applied thereto.

3. An ampul having a neck and having an outwardly flaring mouth beyondsaid neck,. a closure memberaloosely seated in said mouth and closingthe entrance to the neck, said closure having a portion thereofextending beyond the lip of the mouth and having a tongue projectingoutwardly from the body of the member beyond the said lip and providingmeans to be engaged for. dislodging the member from its seat and areadily breakable adhesive medium joining said member and the wall ofthe mouth only.

4. A glass ampul having a contracted neck and having a mouth flaringoutwardly beyond said neck, a substantially spherical .glass closuremember seated loosely in said 'mouth and closing the entrance to saidneck,

a readily breakable adhesive sealing medium joining said closure memberand the wall of the mouth and confined to the area of contact betweenthe member and ampul beyond the opening to the neck, said member havingan outwardly projecting tongue extending beyond the lip of the mouth. A

In witness whereof, I have hereunto set my hand and seal atIndianapolis, Indiana, this 6th day of April, A. D. nineteen hundred andfourteen.
